I'm looking for a mouse with which you can send left and right clicks without having to exert mechanical force in pressing a button. Microsoft seems to be selling three different kinds of 'touch mice' which sound promising, but the reviews are confusing; some claim there are no buttons, some claim there are buttons.

Of the Microsoft Touch Mouse, Arc Touch Mouse and Explorer Touch Mouse, which if any do allow you to make left and right clicks without having to press a mechanical button?
